HARRY CROCKER, OF ESMOND, RHODE ISLAND.

APRON-OILER FOR CONDENSERS.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed February 27, 1914. Serial No. 821,524.

To all whom it may concern:

Be it known that I, HARRY L. CROOKER, a citizen of the United States, and resident of Esmond, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Apron-Oilers for Condensers, of which the following is a specification.

This invention relates to condensers of the type adapted to work in combination with a finishing card for wool, flax, or other similar fibrous material.

Condensers of this character are provided with one or more pairs of aprons usually of leather, between which the ribbons of sliver are passed from the card and rolled into a roving by the opposite oscillations of these aprons.

It is found in practice that a certain quantity of oil is required to be applied to the slivers to render the aprons capable of rolling these slivers into strands or rovings, the

quantity of oil varying according to the quality and character of the stock to be operated upon. By the old methods theoil is applied to the apron by hand, which requires some skill in order to distribute the same uniformly over the surface thereof, and after the oil has been applied the machine is obliged to be run from five to twenty min-' utes according to the amount deposited thereon, in order to permit the oil to soak into the leather and become properly distributed over its surface, and even after this free running of the aprons the first stock that is passed therethrough is quite likely to become oiled too much and the last stock passed through before again applying oil is not oiled enough. In other words, the oil is not applied uniformly to the work and consequently the work itself is not rolled uniform. Among other disadvantages in this old method of oiling the aprons are first, the loss of operating time of the cards While the condensers are being run idle; second, unequal oiling of the aprons and consequent un-uniform rolling of the roving; third, an excessive use and waste of oil.

The object of my present invention is to obviate the above difficulties by providing means for automatically supplying oil to these slivers continuously only as fast as required, and to also provide means whereby the quantity of oil thus applied to, the slivers may be varied according to conditions or to the quality or character of the stock to be run.

By the use of my improved apron oiling device the cards are permitted to run continuously without being obliged to stop for a fresh supply of oil and therefore the loss of production from this stopping is obviated. Second, the oil' is" distributed absolutely equal and evenly at all times and on all parts of the slivers, therefore all of the roving is evenly oiled and a more uniform product is obtained. Third, the labor and expense of time of oiling the aprons by hand is saved, as the oil cups are filled once a day and no other attention need be paid to this system of oiling. Then again from forty 'to siXty per cent. of the oil is saved by a systematic application of the exact amount required.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the appended claims.

Of the accompanying drawings: Figure 1 is a diagrammatic view showing the general outline and arrangement of one form of condenser partially in section as adapted towork in combination with a carding machine. Fig. 2 is a. front elevation, partly in section, illustrating my improved oiling roll operatively mounted between the condenser heads. Fig. 3 is a central longitudinal section of my improved roll. Fig. 4-: is a transverse section of the oiling roll.

Fig. 5 is a side elevation of oneof the roll supporting arms. Fig. 6- is a detail showing one form of adjustable feeding oil cup used for supplying the oiling device.

Referring to the drawings, 10 designates one of. the condenser heads, between a pair of which are mounted the pairs of apron .rolls 11 and 12 over which rolls run the aprons 13 and 14, said aprons are usually and preferably made of leather, and said rolls, as is well known in condensers of this character, are provided with means not shown) for impartingto them an osci1latorvmovement, the rolls 11 moving in one direction while the rolls 12 move in the opposite direction, thereby acting upon the .sliverwhichis caused to enter them by any of the usual methods from the usual card, to roll each narrow ribbon of sliver into a roving sothat it issues from the opposite end in the form of a rolled up strand, whence it is led to and wound upon the spools 16.

My present invention lies in the provision of an automatic oiling device for these slivers, which device is herein shown as comprising a roller 17 constructed with a central tubular shaft 18 extending through the same. On this tubular shaft is mounted a thin metallic perforated cylinder 19 of tin, or other metal the ends of which are supported on the heads 20 and 21 which receive a bearing on and are secured to the tubular shaft 18. This cylinder 19 is somewhat larger than the tubular shaft providing an oil chamber 22 there between, and this said shaft 18 is perforated at intervals within this chamber, so as to permit the oil to pass in through its center and be discharged into will of the operator.

said chamber. Around the outside of this cylinder 19 I have wrapped, wound or laid a strip of felt, or other suitable fibrous material, to receive the oil through the perforations therein and equally distribute the same by capillary attraction. Outside of this felt I have placed another thin metal cylinder 2& preferably of sheet tin, having a perforated outer surface, its ends being also closed by the heads 20 and 21 and around this outer cylinder is wound or laid a layer of finely perforated leather 25 through which perforations the oil from the interior of the roll passes and is deposited from its outer surface upon the moving apron which rotates the roll by contact therewith.

In order to supply oil to the central reservoir of this roll I have mounted the ends of the central shaft 18 in bearings 26 and 27, and have provided backings 28 in each forced into position by the caps 29 on the end of the bearings to prevent the oil from leaking out. Each of these hearings is provided with a supporting arm 30 having a central duct or channel 31 therethrough which leads up to its upper end, which end is provided with a threaded boss 32 into which a large oil cup 33 is screwed. This cup is preferably of the usual sight-feed construction and is provided with the usual shut-off needle 11 and adjustable collar 42 whereby the quantity of oil passing therefrom through the channel into the roll may be nicely regulated and controlled at the The upper end of said arm is also provided with a hub 34: which is mounted upon and secured to a transverse rod 35, by means of set screws 36. This rod is rotatably mounted in suitable bearings 37 at either end, the same being preferably bolted to the condenser heads 10. On this rod is also mounted a finger 38 which extends outward from the collar 39 on the opposite side of the rod from that of the roll supporting arms and the weight 40 is adjustably mounted on said finger for the purpose of counterbalancing the weight of the roll 17 and its supporting arms to regulate the pressure of the roll upon its apron.

In the operation of my improved oiling device the oil is poured into the cup 33 and its feed control is adjusted to permit the required quantity or number of drops per minute to issue therefrom, then runs down through the channels 31 in the arms 30 and enters opposite ends of the roll 17 through the tubular shaft and through its perforations into the chamber 22 therein. Here the rapid rotation of the roll causes the oil to follow the inner sur face of the shell 19 and pass through its perforations into the chamber 22 therein. Here the rapid rotation of the roll causes the oil to follow the inner surface of the shell 19 and pass through its perforations into the felt or other packing of fibrous ma terial 23 on the surface thereof, the capillary attraction of the fibrous material serves to spread the oil uniformly throughout the entire surface of the roll. The oil then passes outward through the outer thin perforated metal shell 24 which provides a hard smooth regular surface upon which the outer facing material of leather is wound or wrapped. The centrifugal force now causes the oil to pass through the pores or perforations of the leather and to be uniformly distributed upon the surface of the moving the oil from here' apron which causes the roll to rotate by contact therewith.

This oiling device may be applied to the upper apron of each pair and the oil from this upper apron is transferred to the lower apron by the rolling contact with the fibers between them.

I have shown and described a roller as one means for oiling the aprons, but any device adapted for automatically distributing oil upon the aprons will fall within the spirit and scope of my invention.
